UNITED STATES PATENT OFFIc GRAlN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 226,677, dated April20, 1880.

Application filed January 22, 1880.

5 ful Improvement in Grain-Harvesters, which improvement is fully setforth in the following specification and accompanying drawings, inwhich- Figure l is afront elevation Fig. 2, a plan; left-side elevation;Fig. 5, a right-side elevation, and Fig. 4 a detail.

' The object of my invention is to hang the reel in such a manner thatit may be readily adjusted, with reference to the sickle-bar, up

or down, or backward or forward, or have its overhanging end dippedtoward the ground or raised farther therefrom, as the case may require;to raise and lower the reaper bodily by.

new and novel means, and to produce other improvements, all hereinafterfully set forth.

In the drawings, A is the frame, 13 the drivingwheel, 0 the drafttongue, D the reel, E the elevating canvas or apron, and F theseat-plank, of an ordinary combined grain The reel-shaft G is supportedby arms I) 1), extending from a horizontal shaft, d, supported inbearings at or near the upper end of a boom-frame, H, which frame orboom is hung upon a rod or shaft, f,

0 held to the reaper-frame by lugs h h. The

boom H is capable of being brought to a vertical position close bythefront side of the main frame A, orof being swung forward at the topso as to overhang the base, in which latter po- 5 sition the reel iscarried at a greater distance in advance of the sickle-bar, as shown inFig. 3.

The reel is rotated by means of a chain, k, upon a sprocket, Z, of thereel-shaft, said chain passing over idlers 6 upon the shaft (1, thence4o downward under other idlers, p, upomor near the shaft f, and back tothe pinion-shaft t, near the driving-wheel. The idlers e an d1),beinglocated upon or near the respective shafts d and f, admit of theboom H being swung forward q or backward without altering the tension ofthe driving-chain 7c.

3 is a serrated bar rising from the seat-plank F, stayed at the top tothe reaper-frame by braces 61, said bar being bent, having its concavitytoward the reel-shaft, as shown in Fig.

3. f is a hand-lever within convenient reach of the driver, being anextension of the reelsupporting arm I), and bent in such a manner as tocross the bar y. This lever f is also serrated, as shown, the serraturesengaging with those of the bar 3 by means of which the reel and boom arelocked or held at any desired position. a

By looking the lever f in one of the upper notches of the bar orlever-restg the reel will be lowered, or if locked in a lower notch ofthe resty the reel will be raised. If the lever be locked to the rest ina notch of the former near the extreme end or handle of the same, theboom will be swayed forward, carrying the reel considerably in advanceof the sickle-bar, or if locked in a notch of the lever remote from thehandle the boom will be folded back against the main frame, bringing thereel close to the sickle-bar. This gives to the reel a universalmovement as regards a vertical plane.

The arm I), Fig. 1, is secured rigidly to the shaft (1, and a shorterarm, 0, is also secured to said shaft, pointing in the same direction asthe arm I), while the arm b (or leverf) is fitted so as to turn freelyupon the shaft d.

The arm 0 is expanded at its end into a transverse slot slightly curvedconcentric with the shaft [1, as shown in- Figs. 3 and 4. 'i is a boltpassing through said slot and the arm I), clamping the two together. Ifthe bolt be loosened, the arm I) may be turned to either of the extremepositions shown in Fig. 4:, which will cause one or the other of theends of the reel-blades to pass over the sickle-bar in advance of theothers and dip the shaft, as shown.

These capabilities of the reel are of great importance in practice,forif the reaper be moving with the wind the standinggrain will leanaway from the sickle-bar, and after being cut will notfall properly uponthe platform. To remedy this the driver may unlock the reel tiltinglever f and draw the boom back against the frame, relocking the lever inthe upper notch of the rest y. This will lower the reel and cause itsblades to move farther over the platform and counteract the effect ofthe wind upon the grain, first, by holding it while standing fairlyagainst the sickle-bar, and, second,

after being cut laying it more evenly upon the platform.

advance of the reaper, it may be straightened: in front of thesickle-bar and brought upon the platform in much better shape by skewingthe reel one way or the other, as shown in Fig. 4,;

to suit the circumstances of the case.

To hold the lever f against the rest y a crank-sh aped rod, n, Figs. 1and 2,is employed, attached to the lever parallel'with 'the same,

and held in hangers just'outside of or over the This rod is held notchesof the said lever. against the blankedge of thezrest y, forcinga notchof the same into a notch of thelever, by

means of a spring, 8, and to throw the xrod back from the lever-rest andunlockthe lever a thumb piece, 0, is employed, by pressing which-thecrank-rod n'isrotated in its bear-' ings back away from the rest y, asindicated bydotted positions in Figs. 2 and 3. :lf the thumb piece 0 bereleased, the spring s'will immediately rotate the rod n against'therest 4 and lock the leverf, as shown in Fig.2.

I is a notched bar lying parallel with the elevating-canvas E,andoperated inia :manner to move the cut grain endwise as-it isrbeingcarried upward, for the purpose of pre The lower:

P is a main driving-gear secured to the driving-wheel, and e a pinionupon :the shaft t,

driven bythe gear P,-from which shaft 25 the 'reel andotherworkin'g'parts of thereaperare driven, said shaft being journaled inboxes attached tothe sills of theframe.

grain-adjuster I, which may be an endless belt upon pulleys instead of abar, as shown, is designed to operate between the outer and innercanvases upon the grain, as above described.

The seat-plank F is bifurcated at its front end, the two branches at andr! of which act as guides for the boom as itis swayed forward andbackward for the purpose of maneuvering the reel, as above set forth.

I claim as my invention- 1. The combination, with the reel-shaft G,shaft (1, and support I), of the slotted arm 0 and adjustable support b,with a fastening, i, by means of which combination the said reelshaftmay be dipped or thrown askew, as set forth.

2. In combination with the reel-shaft G and frame H, a driving-chain, k,for the reel, passin g over idler-pu1leys 0 and e, placed respectivelyon or near the pivotal shafts f and d, for the purpose set forth.

3. In combination with the frame H, a bifurcated seat-plank F, thebranches to and r of which form guides for said frame, substantially asshown. I

- 4. The combination of the notched bars I and L and the connecting-rodu with the fixed bar N, provided with a tooth, 11, substantially asdescribed.

5. A locking device for the lever f and rest y, consisting of a bentshaft, n, resting in suitable hangers, and provided with a spring, 3,and an operating device, 0, for said locking device, substantially asdescribed.

6. A lever, B, and catch-bar s, in combination with the gear P andpinion e, for the purpose set forth.
